mu+SR as a probe of anisotropy in low-dimensional molecular magnets

Abstract:
We describe how muon-spin rotation (mu+SR) can be particularly effective in determining the onset temperature of 3D ordering in low-dimensional molecular magnets, even when the low dimensionality means that this transition is masked in data from bulk thermodynamic probes such as heat capacity measurements. We illustrate the use of mu+SR with various copper-based magnets, including copper pyrazine dinitrate, Cu(C4H4N2)(NO3)(2), which orders below 0. 107 K, and also for the organic radical-ion salt DEOCC-TCNQF(4) which appears to be one of the most ideal examples of 1D S = 1/2 Heisenberg anti ferromagnets yet discovered.
